Rectangular connectors offer vital solutions for a variety of applications. Housings, such as the 776438-2, are designed for stable connections in even the most extreme conditions. This article outlines the 776438-2’s implementation requirements and working principles.

General Specifications and Important Features

The 776438-2 is an environmentally sealed, low-cost, board-mountable system molded in reinforced polyamide. This EMC/ESD (electromagnetic compatibility/ electrostatic discharge) certified housing is designed to contain 10 printed circuit board pins, 8 coaxial contacts, and 2 optical contacts. This allows for a wide range of current capacities, temperature ranges, and frequency bands. Its dimpled walls and snap-on locking flanges provide easy disengagement, while its surface-mounted solderable board flats enhance its board-mountability.

The 776438-2 is also equipped with IP67-grade protection. This ensures its resistance to dust, solvents, abrasives, water, and high-pressure cleaning liquids. The connector’s dielectric strength is rated at 4kV, guaranteeing a rupture-free connection.

Application Fields

Due to its versatility, the 776438-2 is ideal for automotive, communications, medical, industrial, and military applications. More specifically, its efficient power and signal transfer capabilities make it suitable for the mux bus of dashboard systems. It can also be used in entertainment devices, surveillance systems, and smart containers. This housing is also a favorite among optical and electrical diagnostic equipment, as it expertly transfers high-frequency analog signals.

Working Principles

This rectangular connector has a floating, slant spacing design that helps guide mating pieces into place without a breaching the seal. The connection is made by the electrical contacts pushing through housings and being given a 90 degree twist. The housings are then bonded using a levitation or air-gap cushion, ensuring a solid connection. The seals on the housing latch the two components firmly together, ensuring the connection is not lost.

Once all the connections are securely in place, the chamber is filled with a moisture-resistant insulation compound. This raises the insulation resistance between the contacts, protecting them from outside ambient interference.

The 776438-2 rectangular connector also comes with a double-lock mechanism. This prevents the connector from being accidentally released, even when subjected to extreme vibrations.

Conclusion

The 776438-2 housing has a number of features that make it ideal for use in a variety of applications. Its resistant construction, board-mountable design, and dependable protection provide excellent electrical properties for a variety of products.
